I bought a TAFE 45 DI used from a friend. It has two-wheel drive and no bucket. It seems to have plenty of power to do whatever I need it to.
I have used tractors with a bush hog before, and have to say this one excels at it. I really like the handbrake and the foot throttle. Both are very handy ideas. The three-point works well, and at only 1500 RPMs you are turning 540 on the power take-off, which means the strong diesel engine is barely working hard. It is also stingy on fuel!
Overall, I think if you can find one of these for the right price, you should get it.
